v IIVIPROVMENTIN TRAVERSE MOTIONS FOR WINDING AND SPOOLING MACHINERY.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may conce-rn Beit known that I, J oHN E. ArwooD, of Mansfield, in the county of Tolland and State of Gonnecticut, have invented certain new and useful Improvements in Traverse Motions for iVinding'and Spooling Machinery, of which the following is a full, clear, and

exact description, reference being had to the accomguides;

Fignrefi, a side -view of the same; and

Figure 5a transverse section thereof.

' Figure- Gis a view, in perspective, of one of the thread-guidesA detached.

Similar letters of reference indicate corresponding parts.

My invention relates to transverse motions for winding and spooling machinery generally, including the winding of silk, cotton, or other thread, either on spools or in cops, for vmanufacturing or trade purposes.

The invention consists in certain substitutes or means for the eccentric motion heretofore in use, for varying, in a less complicated and in a more perfect or desirable manner, the range of the traverse bar to prevent the motion from commencing and terminating always in the same points, and piling 'up thread near the ends of the spool or coning-shaft, and to remedy all inaccuracies consequent on the wear of themachinery.

The invention also embraces 'a novel construction of the wire-conductors, which serve to direct the silk or thread to the guides on the traverse bar, vwhereby increased lightness is secured and a shield to the guides formed, to prevent the thread from catching under them. l

The invention likewise includes anovel construction of the guides, the same combining lightness and cheapness, with facility of adjustment and :a broad surface, which reduces wear.

By these improvements, also, or certain ol' them, increased lightness generally is secured to the traverse bar, which is an important consideration in machiner of the description referred to.

Referring to the accompanying drawing- A represents a length or section of a traverse bar, and y v l v 'onsly with the rotation of the spools, as usual.

D is the driving-shaft, by which motion is communicated, through frictional gear or otherwise, to the spools, and which serves, also, to convey to the bar its necessary reciprocating action, as follows:

E is a pinion on the shaft D, which pinion gears I with differential. wheels F F', hung to rotate around a'stud, b, independently of each other, for which purpose the one wheel may turn loosely on the stud, vhile tlic other wheel turns around a sleeve on the rst.

The outer one, F, of these wheels, which may have either a greater or alesservnnmber of teeth 'in it than the other wheel, F', has connected with itl the cam G,'by which traverse motion is communicated to the bar A, through an arm, c, as against the reverse action of a spring, d. y

To vary the range of the bar, not as regards its length, but as regards the -peints at which it or its thread-guide commences and terminates its stroke relatively to the spool to meet inaccuracies consequent on wear, and to prevent piling up thread near the ends of the spool and otherwise'to vary the disposition of the thread over thc face ofthe spool, the outer wheel` F, which is kept in contiguity with the inner wheel F by the spring d, or otherwise, has arranged on its innenface a projection, e, against which a cam or sloping-faced disk, j; on the contiguous face of the adjacent wheel F acts to give a slightand gradual lateral motion to the operating-cam G- by reason of the differential velocit-ies of the wheels F and F,.a nd which securesto the traverse bar the required changein its motion without altering its length of stroke.

The inclined wires H, which conduct the thread int-o or on to the guides O, are made double, as seen in figs. 1, 3, and 5 of the drawing, and are retained in shape and position by means of staples g and flattened interposed wires h. l

This construction of the wire-conductors is lighter than a single wire arrangement and forms a shield to the guides C to prevent the thread from catching nnder the guides.

The guides O are also made light, and thus the traverse bar generally relieved of much weight, which is an important consideration.

These guides G furthermore combine cheapness with facility ofadjpustmentand a broad surface for the thread, whereby they are prevented from being quickly worn, said guides being stamped or formed out of sheet metal, and of a hollow or partially rounded forni for the guiding portion of wenn/and a slotted at hase at their end for attachment to and adjustment on the traverse bar, as shown in jigs. 1, 3, and 6 ofthe drawlng.

What is here claimed, and desired to be secured by Letters Patent, is`-` 1. The combination of .the dierential wheels F and F', furnished respectively with they projection e and cam j; the 'pinion E, and the cam Glwith the traverse bar A, substantially as and for the purpose oi' purposes herein set forth.

l2. The wire-conductors H, niade double, in oo nlenc'l, substantially as specified.

bnation with the staples g and. attened interposed wires h, essent-ialiy as shown and described.
